Abstract: A vehicle wheel monitoring device includes a tire pressure monitoring unit, a tire pressure sensor unit disposed at a wheel of the vehicle and a brake pad wear sensor unit disposed at a wheel of the vehicle. The brake pad wear sensor unit includes a brake pad wear sensor and a wireless transmitter configured to receive the signal emitted from the brake pad wear sensor and wirelessly transmit it to the tire pressure monitoring unit. An energy harvesting device is configured to convert energy derived from an external source into electrical power, and to provide the electrical power to the brake pad wear sensor unit and the transmitter. The brake pad wear sensor unit and the tire pressure sensor unit are monitored by the tire pressure monitoring unit.
